POKEMON GO has launched and while fans have been busy trying to discover where Legendary Pokemon like Mew, Articuno and Zapdos will be found, Niantic have revealed a rough guide to their release window plans.

Pokemon Go Legendary Birds and Monsters will not be released until the game is available worldwide

UPDATE ONE: A new Pokemon Go update has confirmed a few facts about the Legendary birds that Pocket Monster trainers have been waiting to find out.

While fans have looked tirelessly for the likes of Mew, Articuno and Zapdos, developers Niantic have now confirmed that they have yet to release them into the wild.

The developers behind Pokemon Go told a sold-out San Diego Comic-Con panel that Legendary types are set to be added to the game but not until a certain milestone is reached.

New information was recently discovered to confirm their existence, fans digging through Pokemon Go game files have found rare Pokemon listed in the game, including Ditto, Mew, Articuno, Moltres and Zapdos.

And Niantic have now confirmed that Legendary Pokemon will not be added to the game until its released in all planned regions.

That means trainers will have to wait until its at least finished its worldwide rollout before they can hope of catching a Mew.

Mewtwo was recently discovered to have a base attack of 284, a large upgrade when compared against Dragonite's 250. It also seems that Mewtwo does not have a capture rate, meaning that a special event or timed movement will be when it become catchable.
